Mercedes wants to bring CarPlay to older vehicles this year

The biggest catch of Apple's CarPlay (aside from platform support) is its limitation to newer vehicles; at last check, most people won't buy a new car just to get better smartphone integration. Mercifully, Mercedes-Benz tells 9to5 Mac that it's planning to deliver an "after market solution" for older cars by the end of 2014. 

Would love to see BMW do something similar.  Getting this technology into older vehicles would be amazing.
